Crate oj_config 

Loads oj.config.{ts,js,mjs,json}.

.json is parsed directly. .ts/.js/.mjs have their TypeScript types stripped with oxc, then evaluate in an embedded QuickJS engine (no Node) with defineConfig and process.env shimmed, capturing the default export and reading it back as JSON. Computed values, ternaries, and process.env all work; the exported object must be JSON-serializable (functions/plugins are out of scope until the plugin system).

Functions

config_defines

Top-level config.define as (name, js-expression) pairs, applied in every environment.

environment_build_bool

A boolean under environments.<name>.build.<field> (e.g. minify, sourcemap), if set: the per-environment build-output override.

environment_defines

config.environments.<name>.define as (name, js-expression) pairs: the per-environment overrides of the Vite Environment API.

load

Load the config from root, or OjConfig::default() if none exists.

resolve_alias

resolve.alias entries (find, replacement) for an environment. Precedence: environments.<name>.resolve.alias merged over top-level resolve.alias. Returns (find, replacement) pairs for the resolver.

resolve_conditions

Package exports/imports condition names for an environment. Precedence: environments.<name>.resolve.conditions > top-level resolve.conditions > the built-in default (browser for client, node for ssr).
